I read ale's guide. That's where I got the 24 from.
thanks guys.
lastly, where can I buy a Rolex rep?
jk lol.
PAM GUIDE is indicating the size at lugs, the other end of the strap depends on the buckle you have or you want to use
The standard buckle of 24mm PAM 029 is a Thumb Nail buckle of 22mm. Therefore you would need a 24/22 strap.
If you want to use a 24mm buckle you would need a 24/24mm strap.
Just that
Regarding Rolex, the correct question is:
Who has the best Sub?
As above said, if you have started with PAMs, most likely you will avoid to wear Rollies. I got five reps Rolex and two gens, after I got used to wear PAMs I never wear my Rollies, not even the gens.
